Here's why:

* Cofactors are non-protein chemical compounds that are required for the proper functioning of an enzyme.

* Minerals are inorganic substances that are essential for the body's functions.

* Many minerals act as cofactors, helping enzymes bind to their substrates or facilitating chemical reactions.

Examples of mineral cofactors:

* Iron: Found in heme, a component of hemoglobin and myoglobin, essential for oxygen transport and cellular respiration.

* Zinc: A cofactor for over 300 enzymes involved in various metabolic processes.

* Magnesium: Essential for energy production, muscle function, and nerve transmission.

* Calcium: Crucial for bone health and involved in muscle contraction and nerve function.

* Selenium: A cofactor for enzymes involved in antioxidant defense.
